“UFC 101: Declaration” takes place Aug. 8 at the Wachovia Center in Philadelphia and airs on pay per view.

In just a two-fight span, Leites, a replacement for injured Rousimar Palhares, goes from a main-event slot at UFC 97 to an un-aired preliminary-card bout at UFC 101.

MMAjunkie.com (www.mmajunkie.com) passed along news of Palhares’ broken tibia earlier this month. Leites was slotted as the replacement just days later, and he was officially added to the UFC 101 fight card.

Leites most recently fought at UFC 97, where he dropped a heavily criticized unanimous decision to UFC middleweight champ Anderson Silva. The Montreal crowd continually booed the five-round title fight and what often appeared to be Leites’ refusal to engage.

The loss snapped the Nova Uniao fighter’s five-fight win streak, which included submission wins over Ryan Jensen and Drew McFedries and a controversial split-decision win over Nate Marquardt. (If not for two questionable point deductions, Marquardt would have earned the decision win.)

Leites, one of the UFC’s top submission fighters, now looks to rebound against Sakara, who hasn’t fought since a September 2008 knockout win over Joe Vedepo. Sakara first joined the UFC in 2005, and it’s been a feast-or-famine endeavor. Three of his four UFC victories have come via first-round knockout, and all four losses have come via first-round stoppage.

Sakara, hoping to gain some ground in the 185-pound division, will now go for his third win in four fights.

With the addition of Leites vs. Sakara, 11 total fights are now slotted for UFC 101, which marks the UFC’s debut in Pennsylvania. The night’s card features a main event between UFC lightweight champion B.J. Penn and top contender Kenny Florian, and the co-main event pits UFC middleweight title-holder Anderson Silva vs. Forrest Griffin in a non-title light-heavyweight fight.

The full UFC 101 card now includes:

As the UFC 189 tour made its last stop in Dublin, featherweight champ Jose Aldo was met with a torrent of abuse from the Irish fans. It might have been unpleasant, but it might also have been just what he needed.
